RooE.

Application filed July 30,

To all whom it may concern:

Be it known that I, GEORGE E. SWENsoN, a citizen of the United States, residing at 4425 Clarissa Street, city of Philadelphia,

-in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Roofs, of which the following is a specification.

This invention relates to roofs and the method of applying roofing material thereto. An objectof the invention is to produce a roof which shall be free from leaks, pleasing in appearance, and which shall be easy to erect.

Another object is to produce a roof which can be economically installed in a rapid and efficient manner without requiring a high de ree of skill or care.

eretofore, it has been old to produce roofing material, which is weatherproof and fireproof, by forming a felt base, saturatin the same with waterproofing material'sucfi as tar or asphalt, coating with a layer of bituminous or other material, and applying a layer of crushed stone or similar material to one side thereof to enhance the wearing qualities. In such cases it has been customstrip along one'edge free from stone in order to facilitate makin a water tight joint.

y invention is especially applicable to roofin material of the character above indicate though it is not restricted to such material. The invention will be clearly understood by reference to the accompanying drawings in which Fig. 1 is a plan view of a strip of roofing material partly broken away.

Fig. 2 is a cross section of a cleat used 1n the installation. a

Fig. 3 is an end view of one modification of the cleat.

Fig. '4 is a plan View of the bottom member of Fig. 3.

Fig. 5 is a section through the roof, partly broken away, showing how it is laid.

Figs. 6 and 7. are perspective views on a small scale illustrating the general appearance of two roofs installed in accordance with this invention.

Fig. 8 is'a side view of Fig. 6 on a some-" what enlarged scale.

On the drawings, reference character 1 i represents a strip of the usual waterproofed roofing material covered throughout the Specification of Letters Patent.

v.and is pressed at Patented June 27, 1922. 1918. Serial No. 247,35

most of its extent with a layer 2 of crushedstone or other wear resisting material, but having an edge portion 3 free from such materlal.

4 represents a cleat which maybe made of somewhat stiff and rigid material, preferably Wood, approximately semi-circular in cross sectlon, to be used for purposes which are to be subsequently described. 5 repre sents the bottom and 6 the top member of a metallic cleat which may be used instead of the cleat 4 in installing the roof. The member 5 is provided with the proper number of nail holes 6 to facilitate fastening it to theroof deck.

The method of installing the roof will be obvious from an inspection of Fig. 5 in WhlCll 7 represents a roof deck with a few of the strips applied thereto. In applying the strips 1 of roofing material to the roof deck 7 down the roof deck with its wear resisting side u permost as shown at 8, Fig. 5. On top 0 this strip is placed a second strip with its wear resisting side turned down and with its so called selvage edge 3 extending some distance beyond the first strip as shown at 9. The rigid cleat 4 is then fastened on top of the two edges by driving nails 10 through the cleat edges 8 and 9 and into the roof deck 7, in selvage edge 3 only will be in contact with the layer of stone on the lower roofing strip when the upper strip is bent around the rigid cleat 4, as indicated. The cleats 4 will thus be parallel to the streams of water which run down the roof as clearly shown in Figs. 6, 7 and 8. After the cleat 4 has been fastened in place the upper side of the selvage edge. 3, and also the cleat 4 may have applied to them a coating of a hot bituminous compound such as asphalt, which will cause a softening of the waterproofing such a manner that the a strip is first laid vertically up and material-in the roofing strips thus assuring a close adherence of the edges of the roofing strips beneath the rigid cleat 4, and also causin the selvage edge 9 to stick to the roof eck 7. The upper roofing strip is then bent around and clings to the cleat- 4 11 so as to stick'to the upper surface of the selvage edge 9. It is obvious that the edge at 9 may be fastened down to the roof deck 7 as by nailing before the bituminous material is applied, and a quantity of hot material for cementing purposes may be applied to the upper surface of the edge of the first strip before either the second strip or the cleat 4 is laid. The

successive strips of roofing material will be tion illustrated in Figs. 3 and 4. The flexible member '5 which is usually made of metal is fastened in a manner similar to that above described in connection with cleat 4, but dueto its flexibility, it will folroof, thus insuring a water tight joint between the-two strips of roofing material beneath it. After the member 5- has been applied and before the roofing strip has been turned over it, the lower edges 6 and 6 of the other member6 are sprung apart and inserted under the side edges of member 5, the hot cementing material applied, and the roofing strip is thenfolded over with its wear resisting side uppermost.

It is obvious that the roof can be so laid that the strips will be turned either in a right hand Or a left hand direction. The change from one to the other sometimes becomes desirable in such places for example, as valleys where a gable roof-or dormer window is built, for by this expedient the water can be made to accumulate at 11 in stead of the other side of cleat 4 where leakage might be more apt to occur.

By the use of. this invention a serious objection to the appearance produced by the usual method of installing ready roofin is obviated. The cleats 4 produce ri ges which relieve the monotony and enhance the appearance, thereby making the roof more attractive as indicated in Figs. 6 and 7 besides holding the .roofing material upon the roof deck in a very effective and secure manner, and insuring permanent contact between the overlapping edges of the strips of roofing material.

If necessary or desirable, the strips may be produced with two selvage edges, one of themv being wider than the other. In this way. the edges may be madeto, overla beneath the cleat 4, without having a ayer of wear resisting material interposed between them, while securing many of the advantages of the usual construction.

Claims: v 1. In a roof of the class described, in

-. combination, a cleat, a strip of roofing material, said strip having crushed stone ap- .plied to one side. leaving a selvage edge,

eata d said'selvage edge lying under said 0 the portion of the strip adjacent said selvage. edge lying over said cleat with the stone covered side uppermost.

2. In a roof of the class described, in combination, a cleat, a strip of roofing material, said strip having crushed stone aption of said selvage edge.

3. Ina roof of the class described, in combination, a cleat, a strip of roofing mate ial, said strip having crushed stone applied to one side leaving a selvage edge, said selvage edge lying under said cleat and the portion of the strip adjacent said selvage being cemented to said cleat, to the roof deck, and to the stone covered edge of a preceding strip of roofing material.

4. In the process of covering a roof the steps which comprise laying two strips of flexible roofing material with their edges overlapping, superposing a cleat upon said edges, applying hot liquid material to said edges, and folding one of said strips over said cleat. H

' 5. In the process of 1 applying flexible roofing material having a wear-resisting surface to a roof deck, the steps which comprise laying a strip of wear resisting roofing material substantially parallel to the roof incline with its wear resisting surface upwards, laying a second strip having a selvage edge extending beyond the edge of the first strip with its wear resisting surface downward, fastening the edges by means of a cleat, and folding the second strip over the cleat, so that its wear resisting surface is exposed. 4

6. In the process of laying flexible roofing material, the step oflaying successive strips of roofing material provided with a wear resisting surface having selvage edges, so that the side of the selvage edge which is adjacent to the wear resisting material of one strip is in contact with the wear .resisting material of another strip.

7 The herein described process which comprises laying a strip of roofing material on a roof'deck substantially parallel to the roof incline, laying another strip on saidfirst strip with its edge extending beyond said first strip onto the roof deck, fastening said'extending edge to the roof deck, applying a cleat on both strips near the edge of the first strip, folding the second extending edge which is fastened to the roof deck. In testimony whereof I aflix my signature.
